BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to the lid of the vacuum bottlesfor closing the opening part on the top of the liquid containers andmore specifically it relates to the lid which does not have to beremoved every time the liquid is poured.

[0003] 2. Prior Art

[0004] The lid is used to close the part for pouring the liquid, whichis the opening part of the liquid container and in most of the cases, itis so constructed as to be attached to the liquid container byscrew-encasing.

[0005] However, the screw-encasing involves rotating the whole part ofthe lid every time the liquid is poured, wherein the lid is rotated tobe removed and attached, thus making the pouring action troublesome.This is how the structure as disclosed in the patent publication No.Hei9-299254 is thought out. In other words, in the center of the lidthere is formed a pouring inlet piercing through from the top to thebottom. According to this construction, the liquid can be poured bysimply opening up the upper lid attached on the upper part of the lid,which upper lid can be opened and closed and thus, the pouring actioncan be convenient as the lid does not have to be taken off. It is notedthat according to the above-mentioned invention, there is no structurefor actively closing the pouring outlet for pouring the liquid. So longas it is used normally, there might be no need to be provided with themeans for closing the pouring outlet, but in case the liquid containershould fall down, the liquid might be spilt out after passing throughthe pouring outlet.

SUMMARY OF THE INVENTION

[0006] The main purpose of the present invention is to prevent theliquid from spilling out while it is easy to pour the liquid into thevacuum bottle and to get rid of any inconvenience.

[0007] This is also to provide a lid of the liquid container with apouring outlet for pouring the liquid into the liquid container to whichit is to be attached, while the pouring inlet is piercing throughvertically and in the below side of the whole part of the said lid thereis formed a pouring outlet for pouring the liquid by inclining theliquid container, together with the closing material for closing thesaid pouring outlet in a manner allowing it to be opened and closed,wherein there is provided a resilient means to push toward the closingdirection in respect of the said closing material and to provide a lidof the liquid container provided with the operating material for openingthe said pouring outlet, while shifting the position of the closingmaterial against the resilient force of the said resilient means.

[0008] When the liquid is poured into the liquid container provided withthe above said lid, the pouring inlet is used while the lid is on. Whenpouring the liquid inside, there is no need to take off the lid, andthus it takes only an easy and simple task to pour the liquid inside.When the liquid is thus poured, the liquid inside will not spill overthrough the pouring outlet even if the liquid container is inclined.This is because the pouring outlet is actively closed by the closingmaterial provided with the resilient force of the resilient means andeven when the liquid container falls down, it is possible to prevent theliquid from spilling over from the pouring outlet.

[0009] When the liquid is poured out, the closing material may beshifted in respect of its position by operating the operating materialto open the pouring outlet. The operating material may be composed of anappropriate means like a pushing button and levers.

[0010] Furthermore, on the top of the said pouring outlet there may beformed a concave part in the form of a funnel so that the liquid can bepoured easily without spilling over.

[0011] Additionally, on the top of the pouring outlet there may beprovided a lid capable of opening and closing by a simple action otherthan a screw-encasing and when the pouring outlet is closed by the saidlid, the liquid may be prevented from spilling out of the pouring outletwhen the liquid container falls down, without having trashes get intothe liquid container or changing the temperature of the liquid. Forinstance, on the top of the lid there is attached a lid part for openingand closing and a retaining part for keeping closed the said lid foropening and closing, wherein below the above said lid part for openingand closing there may be formed a closing protrusion for closing theupper part of the pouring outlet.

[0012] Furthermore, the said operating material may have the encasingpart on one end and on the other end there may be formed a lever forpushing down, provided with the pushing down device. The lever-principlemay be applied and it takes only light force and easy operation.

[0013] In this case, the pushing part may be placed on the upper side ofthe handle formed onto the liquid container. By using the fingersholding the handle and the thumb, the pushing-down lever can be lowered,thus easily pouring the liquid with one hand only.
